YORK, ASSIGNORS TO HUGH YOUNG, OF NEW :lMPROVEMENT iN RECIPRQCATINGDIAMOND-SAW MACHINIES.

Specification forming part of Letters Patent No. 173,709, dated February 15, 1876; application filed October 19, 1814.

To all whom it may concern Be it known that we, JAMES L. YOUNG, of Ancram, in the county of Columbia, New York, HUGH YOUNG, of the city of New York, in the county and State of New York, and H. GEN- GEMBRE HUBERT, of the city of New York, aforesaid, have invented a Reciprocating DiamondS-aw Machine, of which the following is a specification:

This invention relates to that classof machines in whicha s'aw-blade,armed or protected with diamonds,and having the duplex-reciprocating motion described and claimed in the patent of H. Young andJ. L. Young, dated October 18, 1870, and numbered 108,424, is employed for cutting or dividing stone; and it consists in the combination, one with the other, of the difierent parts of said machine, whereby a more complete, efficient, and reliable machine is obtained than those hitherto constructed. 7

In our drawings, Sheet I illustrates the general plan of our diamond-saw machine, and Sheet II is devoted to details of construction of the same.

Figure I represents our reciprocating dia mond-sawmachine in. sectional elevation, through the line T 'l". i Fig. II is a top-view of the same. Fig. IIIrepresents in detail a portion of the sash-end E, pitman P, 850. Bi g. IVis also a detail of the sash, blade, &c. Both of these figures are drawn in section through the line T T. Fig. V is a top view of the pitman and of the crank-pin of the crank-Wheel K. Fig. VI is a detail of the buckle 7:, used for stretching the saw'blade Q,and of the rockblock h. Fig. VII is a transversal section through S S of part of the machine, and Fig. VIII isa top view of the ways H, s'howingt eir position between the posts A, sected at L \J.

The frame of our reciprocating diamond-saw machine is composed of the posts A, the pieces A and A, and of such braces and blocks s are required to make a rigid and permanent frame-work, the whole properly bolted and stayed by iron bolts in such a manner that the posts A will retain a perfectly erect or perpen, dicular position and the middle pieces A .a true horizontal position. The lower end of the posts A are imbedded in suitable foundations, or fastened to proper framing, to insure stability and guard against undue vibration of the frame. Y and L are vertical guides, moun ted and fastened to the posts A, for the purpose of guiding the ways H in a vertical direction. H are the horizontal ways, or frames, which are fitted properly between the guides Y and II with suitable gibs, in such a manner that said ways H can move freely in a vertical direction, but cannot move either sidewise nor lengthwise of the machine. t t are screws, with collars at top end, passing through holes in the pieces A and ban gin g from the same by their collars restingupon suitable friction-steps. The top ends of the screws 13 are provided with suitable gearings, bevel-wheels, '&c., toimpart a rotary motion to the screws t, and the several screws tare connected together so as to move simultaneously. The screws 25 have nuts fastened to or upon which rest the ways H, in such a manner as to support said ways H in a per fectly horizontal position, and the connections between thescrews t, by giving to them all and at the same time a movement of rotation,

will cause the two ways H to be elevated or lowered, and yet retain at all times a perfectly horizontal position. a I

We have represented in our drawings the bevel-wheels, pinions, shafts, ratchet-wheels, lever, links, eccentric, hand-crank, and pulleys which are, or may be, used for moving the ways H up ordown, either by power, by hand, or by the action of the shaft X. These we have thought necessary to illustrate the working of our improved machine, but we do not claim any novelty in this arrangement for working the screws t.

The sash E E E is mounted upon suitable slide-blocks, B, havingproper adjustable gibs to regulate the position of said blocks B upon the ways H in such a manner as to allow the sash E E E to move with ease and be guided in arectilineal direction upon said slides H, and in a perfectly parallel relation to the longitudinal central line of the machine.

The combination of the frame A A A, the guides Y L T, the screws 2?, (connected as described-,) and of the ways H with the sash E E E enables us to impart a correct rectilindiamonds or other hard stones, in any ordinary or improved manner, and which receives, besides the reciprocating motion imparted thereto by the motion of the sash E E E, the push or lift motion described in the aforesaid Youngs patent, by means of the following mechanical combination:

' k are buckles or tension-bolts, which are used for stretching the blade Q. These buckles 70 are pivoted to the blade Q by steel pins, and they pass through rock-blocks h, having angular or knife-edges next to the bearingplaces on the sash-ends E, so as to insure a perfect bearing of the nuts of the buckle is upon the rock-blocks h, and allow, of the blade Q being depressed or pushed downward out w of its tensile line without causing friction on the blocks h. q are pushers or sliding pieces, guided top and bottom, and provided with friction-wheels at top. S are cam-levers, pivoted upon pins in the sash-ends E, the cam part of the camvlevers S so acting upon the wheels of the pushers q that, when the camleversare rocked to the right, they will cause the pushers q to push the blade Q down away from the levers S, and when-the said leversS are rocked to the left, they will release the pushers q and allow the blade Q to rise and return to its original position. J is a link-rod connecting the cam-levers S, one with the other, to insure a simultaneous action of said levers S, and a; is a link connecting both levers S to the lever O, for operating the said cam-levers S. O is a lever, pivoted at top to a hired point on the sash-end E, and at bottom connected to the rod N. The rod N is, in turn, connected to the pin of a small crank, m, keyed fast'to the crank-pin M of the crank-wheel K, and guided with proper slide-boxes fastened to the pitman P, so as to follow the motion of said pitman P and yet slide freely lengthwise therewith, obeying the action of the small crank m. X is the main shaft, mounted in suitable pillow-blocks upon substantial foundations, and having suitable pulleys to communicate to it a rotary motion. The small crank m is keyed upon the crank-pin M in such a position, relatively to the main crank K and.

sash E E E, that it will move the rod Nand act upon the cam-levers S in such relation to the reciprocating motion of the said sash E E E as to cause the blade Q to be pushed down, held 'down, and released in the proper portion of its reciprocating motion for the best working of said blade-that is to say, that it will push the blade Q down when at the one end of a stroke thereof, hold it down during the motion of the blade in one direction, release and allow said blade to rise at, or nearly at, the other end of the stroke thereof, and leave it up during all the return-stroke, inorder to operate thediamonds set in or protecting the blade Q, in accordance with requirements of and in the manner described and claimed in theaforesaid Patent N 0. 108,424, issuedto Young October 18, 1870.

We claim :no novelty for any of the individual parts which we have been obliged to describe herein in detail so as to explain the relation of our improvement to the whole machine, nor do we claimany novelty in the motion of the blade'Q but I What we do claim as our invention, and desire to secure by Letters Patent, is-

In diamond saws for cuttingstone, where the blade is to receive the duplex motions claimed in the Letters Patent of Youngs, 0ctoher 18, 1870, and No. 108,424-

1. The combination of the ways H, screws t,

slide-blocks B, sash E E E, and blade Q,.sub-

stantially as'illustrated and described, tofobtain the rectilineal and parallel motion of the said blade Q, as herein set forth.

2. The combination of the buckles vk, rockblocks h, and blade Q, substantially as described, to allow of thesaid blade .Q receiving the push .or lift motion hereinmentioned. I

3. Transmitting the power for effecting the aforesaid push or lift motion of the blade Q from the shaft X through the same crankwheel Kwhich is used for imparting to the sash E E E and blade Q theabove-mentioned rectilineal parallel motion, substantially as and for the purpose herein specified.
